This 10×54 Calcite pH Correction Vessel is a complete filtration unit designed to raise the pH of acidic water through natural contact with Calcite media. Ideal for borehole, rainwater, or acidic municipal water, the system helps neutralise corrosion-causing acidity, protecting plumbing, geysers, fixtures and appliances.

Supplied with 2 × 25 kg bags of Calcite media (not pre-loaded), the system includes a durable FRP pressure vessel, flow-through head (standard), and internal riser with top and bottom strainers. A manual backwash head is available as an optional upgrade, allowing easy periodic cleaning of the media bed.
